Abstract
The utility model discloses a double-welded corrugated pipe with a single welding spot. The corrugated pipe comprises a corrugated pipe body, the periphery of the corrugated pipe body is coated by a sleeve net, the inner side of the axial end of the corrugated pipe body is connected with a connecting pipe, the outer side of the axial end of the corrugated pipe body is connected with the end of the sleeve net, and the outer side of the end of the sleeve net is provided with a pressing ring. The connecting pipe and the pressing ring are connected to the inner side and the outer side of the axial end of the corrugated pipe body respectively, the corrugated pipe body is connected with other pipes through the connecting pipe, the pressure-bearing capacity of the end of the corrugated pipe body is thoroughly improved by the pressing ring, and manufacturing cost is greatly reduced as fewer parts are used on the premise of simultaneously ensuring the pressure-bearing capacity and connecting performance.
Description
Technical field
The utility model relates to a kind of bellows, needs to tolerate the bellows of certain pressure specifically.
Background technique
Bellows is a kind of housing with cylinder-shaped thin wall wrinkle of a plurality of transverse waves, and bellows has elasticity, and energy under pressure, axial force, transverse force or moment of flexure effect produces displacement.With extensive, predominant use is the measuring cell as pressure measuring instruments to bellows, converts pressure to displacement or power in instrument and apparatus.The bellows tube wall is thinner, and sensitivity is higher, and measuring range is that tens of handkerchiefs are to tens of MPas.Because all multi-link advantage of bellows, cause the use amount of present bellows to increase year by year, how guarantee to reduce under the prerequisite of anti-pressure ability manufacture cost cost those skilled in the art be badly in need of the technical problem that overcomes, and how to improve the utilization of bellows aspect refrigerant recovering.
China's utility model patent patent No. 200720302931.2 discloses a kind of double-wall corrugated pipe, and it comprises bellows, and described bellows is double-wall corrugated pipe, and the enlarging circle in the enlarging of its double-wall corrugated pipe is the lenticular ring stiffener of step.This kind bellows is not mentioned the correlation technique prompting that how to reduce manufacture cost.
Summary of the invention
The utility model provides that a kind of simple in structure, long service life, bearing capacity are strong, low cost of manufacture, be suitable for the bellowss of the two welding of single solder joint of refrigerant recovering industry.
The bellows of the two welding of a kind of single solder joint comprises bellows, and the bellows periphery is coated with net, and described bellows axial end portion inboard is connected with adapter, and the bellows axial end portion outside is connected with the end of net; The outside, end of described net is provided with trim ring.This kind bellows connects respectively by the inside and outside both sides at the bellows axial end portion to be taken over and trim ring, connect other pipelines by taking over, and trim ring has thoroughly improved the bearing capacity of corrugated tube end, the Placement of this kind bellows is under the prerequisite of taking into account bearing capacity and switching performance, because component are few, greatly reduce manufacture cost.
The end end face of described net is concordant with the axial end portion end face of trim ring and bellows, this kind end face flush configuration has been evaded traditional bellows on connecting, the net end is not often in the concordant technology cognition of the axial end portion end face of bellows, this kind do not also have the basis of link to form in the end end face outside that the concordant technology cognition of the axial end portion end face of bellows is based on the conventional construction net, and this experiment novel be that the end end face of net is concordant with the axial end portion end face of trim ring and bellows, be not connected with other links, when reducing manufacture cost, improved aesthetics and the usability of product.
Be stainless steel material as the preferred described bellows of structure, trim ring, improve the compressive strength of bellows.The adapter material is red copper, the chemical property quite stable of copper, is difficult for being corroded.The intensity of copper pipe is more much higher than plastic tube, can bear sizable pressure; And the steel pipe that compares, copper pipe has good toughness again, in stronger frost heave and under impacting also not the crack, do not fracture.The fusing point height of copper; even the medium temperature of transmission is up to 200 ℃; also can work on long-term safety ground; has good permeability resistance; in the using process; its surface can form one deck compact structure, not by the protective film of medium dissolves, no matter be that grease, carbohydrate, bacterium and virus, harmful liquid, oxygen or ultraviolet ray all can not be passed it and then be corroded tube wall.
Described trim ring axial end portion is connected with net, bellows argon arc welding; Described trim ring axial end portion is connected with the adapter soldering.Above-mentioned two kinds of Placements have formed the peculiar technical characteristics of the two welding of the utility model list solder joint, this kind Placement since at first the trim ring axial end portion be connected with net, bellows argon arc welding, then the trim ring axial end portion is connected with the adapter soldering, form two kinds of welding manners of a solder joint at the trim ring axial end portion, because the temperature of argon arc welding is higher than soldering, there is argon arc welding to connect trim ring, net, bellows earlier, connect trim ring and adapter by soldering again, improved the connective stability of trim ring, net, bellows and adapter.
The utility model connects respectively by the inside and outside both sides at the bellows axial end portion to be taken over and trim ring, connect other pipelines by taking over, and trim ring has thoroughly improved the bearing capacity of corrugated tube end, under the prerequisite of taking into account bearing capacity and switching performance, because component are few, greatly reduce manufacture cost.
Description of drawings
Fig. 1 looks the sectional structure schematic representation for the bellows master of the two welding of the utility model list solder joint.
Embodiment
Bellows referring to the two welding of a kind of single solder joint of accompanying drawing 1 the utility model, comprise bellows 4, bellows 4 peripheries are coated with net 5, and bellows 4 axial end portion inboards are connected with takes over 2, and the bellows 4 axial end portions outside is connected with the end of net 5, and the outside, end of net 5 is provided with trim ring 3.
End end face as the preferred net 5 of structure is concordant with the axial end portion end face of trim ring 3 and bellows 4.Trim ring 3 axial end portions are connected with net 5, bellows 4 argon arc weldings and are positioned at solder joint 1; Trim ring 3 axial end portions with take over 2 solderings and be connected and be positioned at solder joint 1.
For overall performance bellows 4, the trim ring 3 that improves bellows is stainless steel material.Taking over 2 materials is red copper.
